WARREN A. SANDERS, OF HAMILTON, OHIO.

ECCENTRIC.

SPECIFICATION forming'part of Letters PatentNo. 768,695, a ed A g s 30, 1904.

Original application filed January 11, 1904, Serial No. 188,473. Divided and this application filed March 18,1904. Serial I No. 198,73 (No model.)

To all whom, it may concern:

Be it known that I, XVARREN A. SANDERS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, (post-oflice address, No. 303, Hamilton, Ohio,) have invented certain new and useful Improvements in Eccentrics, of which the following is a specification.

This invention relates'to an eccentric devised with particular reference to the production of reciprocations at high speedas, for instance, in the production of rapid shaking motions about machinery or in recipr0cat-' ing the long brushes of paper-coating machines.

The invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a face View, with parts broken away, of an eccentric embodying my invention; and Fig. 2, avertical section of the same.

In the drawiugs,1 indicates the body of the eccentric considered as a whole; 2, the eccentric-strap, diametrically divided, as usual; 3, the eccentric-rod, attached, as usual, to this strap; 4:, the usual joint-bolts uniting the two members of the strap; 5, a false hub adapted to fit the shaft'on which the eccentric is to be mounted, this hub having wing-flanges seating against the face of the eccentric; 6, bolts through slots in the flanges of the hub and into the eccentric to serve in clamping the hub to the eccentric and to permit of the shifting of the hub across the face of the eccentric in order to adjust the stroke, the central portion of the eccentric being open or slotted to permit the shifting of the eccentric relative to the shaft; 7, one of the side halves of the body of the eccentric, which is split in a plane at right angles to its axis; 8, the other side half of the body of the eccentric; 9, the joint between the two halves; 10, rivets securing the two halves firmly together; 11, the peripheral flanges of the eccentric, the strap engaging between these flanges as usual, except that the groove between the flanges is very much deeper than usual and much greater in depth than that portion of the strap which projects into the groove; 12, a phosphor-bronze tire disposed in the bottom of the groove of the eccentric; 13, a phosphor-bronze bushing for that portion of the eccentric-strap surrounding the groove in the eccentric, and 14 a series of antifriction-rolls disposed in the groove of the eccentric around the tire and within the bushing.

The stroke of the eccentric can be readily adjusted by shifting the false hub upon the body of the eccentric. The splitting of the eccentric in a plane at right angles to its axis permits of thetire being placed in position and permits, if desired, of the division of the bushing or even of the strap being dispensed with and permits of the rolls being placed in position'after the complete strap is connected with one-half of the body of the eccentric. The flanges 11 of the eccentric directly engage and give support to the sides of the tire, the sides of the bushing, the ends of the rolls, and the sides of the strap.

This application is a division of an application filed by me on January 11, 1904, Serial No. 188,473.

I claim as my invention The combination, substantially asset forth, of an eccentric divided in its plane of revolution and provided with peripheral flanges, a strap engaging sidewise between said flanges,

a tire disposed upon said eccentric and having its sides engaged by said flanges, a bushing disposed in said strap and having its sides engaged by said flanges, a series of rolls disposed between the tire and bushing and having their ends engaged by said flanges, means for rigidly uniting the two divisions of the eccentric, a false hub engaging one of the divisions of the eccentric, and means for adjustably securing said hub in position upon its division of the eccentric.
